The echoing of the porcelain room wasn't too harmful to your ears, you quite enjoyed the sound.
Sam, Dean, and Castiel were investigating a few disappearances where people would be found dead; But their bodies would vanish from the Morgue. It was weird, who was stealing bodies from the morgue?.. Even weirder, there would always be watery footprints on the floor, and the cameras would short circuit every time the door opened and the suspect walked inside.
At the hotel the three were staying at, there was always these three young ladies giggling about a "sexy sea monster" they saw down at the beach. Laying in the sand, or floating atop the waves as they crashed over each other and the "sea monster" would vanish again. Sam, Dean, and Cas thought it was worthy checking out, considering there was water in the Morgue and the fact these girls were mentioning a "sea monster". Water, sea, it connected. They had to explore all possible options before they were to just leave.
Sam, Dean, and Castiel reached the lobby, walking out of the building and driving down to the beach. It wasn't a long drive, merely a minute or two, but it was late at night and dark. As the three stepped out of the Impala, they could smell the ocean. Hear the waves. They all walked down to the sand dunes, watching the waves come up higher and higher.
